Yes, this. I've been filtering my feed a lot and I frequently check communities info and this back closing behavior gets me to have to reopen often if I don't remember to tap the arrow instead.
Even better please add "about community" and "about instance" to the main feed context options (three dots button). I wish I could customize it, as it has block instance but I can't see instance name without opening and I don't want to risk blocking "lemmy.world" lol
